Music Listening Among Postoperative Patients in the Intensive Care Unit: A Randomized Controlled Trial with Mixed-Methods Analysis.

Background: Music listening may reduce the physiological, emotional, and mental effects of distress and anxiety. It is unclear whether music listening may reduce the amount of opioids used for pain management in critical care, postoperative patients or whether music may improve patient experience in the intensive care unit (ICU).

Methods: A total of 41 surgical patients were randomized to either music listening or controlled non-music listening groups on ICU admission.

Premenstrual Dysphoric Disorder Symptoms Following Ovarian Suppression: Triggered by Change in Ovarian Steroid Levels But Not Continuous Stable Levels.

Objective: Premenstrual dysphoric disorder (PMDD) symptoms are eliminated by ovarian suppression and stimulated by administration of ovarian steroids, yet they appear with ovarian steroid levels indistinguishable from those in women without PMDD. Thus, symptoms could be precipitated either by an acute change in ovarian steroid levels or by stable levels above a critical threshold playing a permissive role in expression of an underlying infradian affective "pacemaker." The authors attempted to determine which condition triggers PMDD symptoms.

Depression during the menopause transition: impact on quality of life, social adjustment, and disability.

The impact of depression on quality of life (QOL) and social support has neither been well characterized in clinical samples of women with perimenopausal depression (PMD) nor have the relative contributions of depression and other menopausal symptoms (e.g., hot flushes) to declining QOL been clarified.

Neurobehavioral Abnormalities in the HIV-1 Transgenic Rat Do Not Correspond to Neuronal Hypometabolism on 18F-FDG-PET.

Motor and behavioral abnormalities are common presentations among individuals with HIV-1 associated neurocognitive disorders (HAND). We investigated whether longitudinal motor and behavioral performance in the HIV-1 transgenic rat (Tg), a commonly used neuro-HIV model, corresponded to in vivo neuronal death/dysfunction, by using rotarod and open field testing in parallel to [18F] 2-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET). We demonstrated that age-matched non-Tg wild type (WT) rats outperformed the HIV-1 Tg rats at most time points on rotarod testing.

5α-Reductase Inhibition Prevents the Luteal Phase Increase in Plasma Allopregnanolone Levels and Mitigates Symptoms in Women with Premenstrual Dysphoric Disorder.

Changes in neurosteroid levels during the luteal phase of the menstrual cycle may precipitate affective symptoms. To test this hypothesis, we stabilized neurosteroid levels by administering the 5α-reductase inhibitor dutasteride to block conversion of progesterone to its neurosteroid metabolite allopregnanolone in women with premenstrual dysphoric disorder (PMDD) and in asymptomatic control women. Sixteen women with prospectively confirmed PMDD and 16 control women participated in one of two separate randomized, double-blind, placebo-controlled, cross-over trials, each lasting three menstrual cycles.

Effects of Estradiol Withdrawal on Mood in Women With Past Perimenopausal Depression: A Randomized Clinical Trial.

Importance: Perimenopause is accompanied by an increased risk of new and recurrent depression. The coincidence of declining ovarian function with the onset of depression led to the inference that "withdrawal" from physiologic estradiol levels underpinned depression in perimenopause. To our knowledge, this is the first controlled systematic study to directly test the estrogen withdrawal theory of perimenopausal depression (PMD).

Pituitary adenoma with paraganglioma/pheochromocytoma (3PAs) and succinate dehydrogenase defects in humans and mice.

Context: Germline mutations in genes coding succinate dehydrogenase (SDH) subunits A, B, C, and D have been identified in familial paragangliomas (PGLs)/pheochromocytomas (PHEOs) and other tumors. We described a GH-secreting pituitary adenoma (PA) caused by SDHD mutation in a patient with familial PGLs. Additional patients with PAs and SDHx defects have since been reported.

Reliability of the adult myopathy assessment tool in individuals with myositis.

Objective: The Adult Myopathy Assessment Tool (AMAT) is a 13-item performance-based battery developed to assess functional status and muscle endurance. The purpose of this study was to determine the intrarater and interrater reliability of the AMAT in adults with myositis.

Methods: Nineteen raters (13 physical therapists and 6 physicians) scored videotaped recordings of patients with myositis performing the AMAT for a total of 114 tests and 1,482 item observations per session.

Bone mineral density in young women with primary ovarian insufficiency: results of a three-year randomized controlled trial of physiological transdermal estradiol and testosterone replacement.

Context: Women with primary ovarian insufficiency have significantly lower serum estradiol and T levels compared with regularly menstruating women. They also have significantly reduced bone mineral density (BMD).

Objective: The objective of the study was to evaluate the efficacy of hormone replacement in maintaining BMD in these young women.

Effects of physiologic testosterone therapy on quality of life, self-esteem, and mood in women with primary ovarian insufficiency.

Objective: Women with primary ovarian insufficiency (POI) display low androgen levels, which could contribute to mood and behavioral symptoms observed in this condition. We examined the effects of physiologic testosterone therapy added to standard estrogen/progestin therapy on quality of life, self-esteem, and mood in women with POI.

Methods: One hundred twenty-eight women with 46,XX spontaneous POI participated in a 12-month randomized, placebo-controlled, parallel-design investigation of the efficacy of testosterone augmentation of estrogen/progestin therapy.

Effects of pharmacologically induced hypogonadism on mood and behavior in healthy young women.

Objective: The relationship between depression and estrogen withdrawal remains controversial. The authors examined the effects of gonadotropin-releasing hormone agonist-induced ovarian suppression on mood, sleep, sexual function, and nighttime hot flushes. They focused on whether participating women experienced clinically significant depressive symptoms and whether specific symptoms associated with hypogonadism (nighttime hot flushes and disturbed sleep) increased susceptibility to depression.

A comparison of clinicians' access to online knowledge resources using two types of information retrieval applications in an academic hospital setting.

Objective: The research studied whether a clinician's preference for online health knowledge resources varied with the use of two applications that were designed for information retrieval in an academic hospital setting.

Methods: The researchers analyzed a year's worth of computer log files to study differences in the ways that four clinician groups (attending physicians, housestaff physicians, nurse practitioners, and nurses) sought information using two types of information retrieval applications (health resource links or Infobutton icons) across nine resources while they reviewed patients' laboratory results.

Results: From a set of 14,979 observations, the authors found statistically significant differences among the 4 clinician groups for accessing resources using the health resources application (P<0.

In a model of Batten disease, palmitoyl protein thioesterase-1 deficiency is associated with brown adipose tissue and thermoregulation abnormalities.

Infantile neuronal ceroid lipofuscinosis (INCL) is a fatal neurodegenerative disorder caused by a deficiency of palmitoyl-protein thioesterase-1 (PPT1). We have previously shown that children with INCL have increased risk of hypothermia during anesthesia and that PPT1-deficiency in mice is associated with disruption of adaptive energy metabolism, downregulation of peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), and mitochondrial dysfunction. Here we hypothesized that Ppt1-knockout mice, a well-studied model of INCL that shows many of the neurologic manifestations of the disease, would recapitulate the thermoregulation impairment observed in children with INCL.

A 25-year study of the clinical and histologic outcomes of hepatitis C virus infection and its modes of transmission in a cohort of initially asymptomatic blood donors.

Background: A total of 738 volunteer blood donors who were positive for anti-hepatitis C virus (HCV) were assessed for risk factors and outcomes for up to 15 years within the study and up to 54 years from the estimated onset of infection.

Methods: A third-generation recombinant immunoblot assay (RIBA) was performed to distinguish true from false anti-HCV reactivity. Findings of HCV polymerase chain reaction classified subjects as having chronic HCV infection or as having recovered.

Multisite reproducibility of the broth microdilution method for susceptibility testing of Nocardia species.

Antimicrobial susceptibility testing (AST) of clinical isolates of Nocardia is recommended to detect resistance to commonly used antimicrobial agents; such testing is complicated by difficulties in inoculum preparation and test interpretation. In this study, six laboratories performed repetitive broth microdilution testing on single strains of Nocardia brasiliensis, Nocardia cyriacigeorgica, Nocardia farcinica, Nocardia nova, and Nocardia wallacei. For each isolate, a total of 30 microdilution panels from three different lots were tested at most sites.

Mouse current vocalization threshold measured with a neurospecific nociception assay: the effect of sex, morphine, and isoflurane.

Sine-wave electrical stimulation at frequencies 2000, 250, and 5Hz to respectively evaluate Aβ, Aδ, and C sensory neurons has recently been added to the armamentarium used to evaluate sensory neurons. We developed an automated nociception assay using sine-wave stimulation methodology to determine current vocalization threshold in response to 2000, 250, and 5Hz and examine the effects of sex, analgesics, and anesthetics in mice. At baseline, males had significantly higher mean current vocalization thresholds compared with female mice at 2000, 250, and 5Hz (p≤0.

Conducting HIV research in racial and ethnic minority communities: building a successful interdisciplinary research team.

HIV infection occurs in disproportionately high rates among racial and ethnic minorities in the United States, making it imperative that individuals from these groups be included in research studies. However, it is often difficult to recruit HIV-infected Hispanics and African Americans in clinical trials, but a skilled interdisciplinary team that includes researchers with racial and ethnic diversity can help. This article describes a successful approach for building an interdisciplinary team that values the participation of racial and ethnic minorities in clinical trials and has the skills to work with these groups.

Depression in women with spontaneous 46, XX primary ovarian insufficiency.

Context: A high prevalence of depressive symptoms is observed in women with primary ovarian insufficiency (POI) compared with women in whom the menopause is normally timed. Indeed, studies suggest that depression and/or its pharmacological treatment contribute to the onset of POI.

Objectives: We characterize the prevalence of psychiatric disorders and the timing of onset of clinically significant depression relative to both the diagnosis of POI and the onset of menstrual irregularity in women with POI.

Risks of propofol sedation/anesthesia for imaging studies in pediatric research: eight years of experience in a clinical research center.

Objectives: To quantify the incidence of adverse events associated with anesthesia given for research-driven imaging studies and to identify risk factors for those events in pediatric research subjects.

Design: Retrospective cohort study.

Setting: National Institutes of Health Clinical Center.

Validation of manual muscle testing and a subset of eight muscles for adult and juvenile idiopathic inflammatory myopathies.

Objective: To validate manual muscle testing (MMT) for strength assessment in juvenile and adult dermatomyositis (DM) and polymyositis (PM).

Methods: Patients with PM/DM (73 children and 45 adults) were assessed at baseline and reevaluated 6-9 months later. We compared Total MMT (a group of 24 proximal, distal, and axial muscles) and Proximal MMT (7 proximal muscle groups) tested bilaterally on a 0-10 scale with 144 subsets of 6 and 96 subsets of 8 muscle groups tested unilaterally.

Children with infantile neuronal ceroid lipofuscinosis have an increased risk of hypothermia and bradycardia during anesthesia.

Background: Neuronal ceroid lipofuscinoses (NCLs) are a group of autosomal recessive neurodegenerative diseases characterized by lysosomal accumulation of autofluorescent material in neurons and other cell types. The infantile NCL (INCL) subtype is rare (1 in >100,000 births), the most devastating of childhood subtypes, and is caused by mutations in the gene CLN1, which encodes palmitoyl-protein thioesterase-1.

Methods: To investigate the incidence of hypothermia and bradycardia during general anesthesia in patients with INCL, we conducted a case-control study to examine the perianesthetic course of patients with INCL and of controls receiving anesthesia for diagnostic studies.

Association of interleukin-15-induced peripheral immune activation with hepatic stellate cell activation in persons coinfected with hepatitis C virus and HIV.

Hepatic stellate cells (HSCs) mediate hepatitis C virus (HCV)-related liver fibrosis, and increased HSC activation in human immunodeficiency virus (HIV)/HCV coinfection may be associated with accelerated fibrosis. We examined the level of HSC activation in HIV/HCV-coinfected and HCV-monoinfected subjects and its relationship to the level of activation and gene expression of peripheral immune cells in coinfected subjects. HSC activation levels positively correlated with peripheral CD4+ and CD8+ T cell immune activation and were associated with enhanced interleukin-15 (IL-15) gene expression, suggesting a pathogenic role for IL-15-driven immunomediated hepatic fibrosis.

The psychosocial transition associated with spontaneous 46,XX primary ovarian insufficiency: illness uncertainty, stigma, goal flexibility, and purpose in life as factors in emotional health.

Objective: To examine factors associated with emotional well-being in women with spontaneous primary ovarian insufficiency.

Design: Cross-sectional and case-control study.

Setting: Clinical research center, national U.

Return of chronic pelvic pain from endometriosis after raloxifene treatment: a randomized controlled trial.

Objective: To evaluate whether 6 months of raloxifene was effective in treatment of chronic pelvic pain in women with endometriosis.

Methods: Women with chronic pelvic pain and no endometriosis treatment for 6 months underwent laparoscopy for excision of all lesions. Those with biopsy-proven endometriosis were randomly allocated to raloxifene (180 mg) or placebo daily.

Functional well-being is positively correlated with spiritual well-being in women who have spontaneous premature ovarian failure.

Objective: To examine the relationship between spiritual well-being and functional well-being in women who have spontaneous premature ovarian failure.

Design: Cross-sectional.

Setting: The Mark O.
